The Detroit Lions have made a change to their roster the night before Sunday's game against the Minnesota Vikings. Specifically, a change has been made in the secondary. The Lions have released cornerback Jerome Murphy and signed safety Ricardo Silva from the practice squad.
Silva spent most of last season on the practice squad despite having a good preseason. He got some time on the active roster at the end of the 2011 season, and now he's getting another shot at being on the 53-man roster. The move to sign Silva indicates that Amari Spievey, who showed up as questionable on the final injury report, probably won't be able to play on Sunday.
Murphy just joined the Lions last week when Kevin Barnes was released. Murphy was claimed off waivers by the Lions after being let go by the New Orleans Saints. Clearly, the Lions felt he was expendable, which is why he was released in favor of Silva, who can provide more depth at safety.
